Parametric study of a single-slope solar distiller designed for the arid region of Biskra (Algeria)
Main Article Content
Abstract
This experimental study, conducted at the Scientific and Technical Research Center on Arid Regions in Biskra, Algeria, measured hourly parameters-including ambient temperature, wind speed, solar radiation on the glass surface, and distillate yield-across three basin water depths (0.34 cm, 0.45 cm, and 0.57 cm, equivalent to 1.5, 2, and 2.5 liters of water mass, respectively). Over a three-day period, the results highlighted that solar still efficiency hinges on balancing regional meteorological factors (sunlight, clouds, thermal gradients) with water depth. Shallow designs excel in sunny areas, while moderate depths adapt to cloudy/variable climates. Excessive depth harms output.
